Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671388, here are decompositions:

7 + 8671381 = 8671388
67 + 8671321 = 8671388
97 + 8671291 = 8671388
139 + 8671249 = 8671388
157 + 8671231 = 8671388
211 + 8671177 = 8671388
241 + 8671147 = 8671388
331 + 8671057 = 8671388

Showing the first eight; more decompositions exist.
